船舶机舱通风之----热油锅炉空气消耗计算
ISO 8861-1998机舱通风里面,有关热油锅炉燃烧空气的描述是英文的,
即In a case where the capacity of a boiler or a thermal fluid heater is known in kilowatts,the
following formula is used:
qb= Q*mfs*maf/p
where
Q is the maximum continuous rating of the boiler(s),in kilowatts;
ms is the total steam capacity (maximum continuous rating) of the boiler(s),in kilograms
per second;
mfs is the fuel consumption,in kilograms of fuel per kilogram of steam,or in kilograms of
fuel per second per kilowatt of thermal capacity;
NOTE — Where specific data are not available,mfs = 0,077 kg/kg may be used for the calculation
if the steam capacity is known.If the thermal capacity is known,mfs = 0,11 kg s-1 kW-1 may be used.
maf is the air requirement for combustion,in kilograms of air per kilogram of fuel;
NOTE — Where specific data are not available,maf = 15,7 kg/kg may be used for calculation.
r = 1,13 kg/m3 (i.e.the density of air,at + 35 °C,70 % RH and 101,3 kPa).
这里当锅炉是热油锅炉时,Q、Mfs、Maf怎么选取,

Answer 1

吃喝完毕,谁也没说句应酬话,我就走到一扇窗子跟前去看看天气.我见到一片悲惨的景象：黑夜提前降临,天空和群山混杂在一团寒冽的旋风和使人窒息的大雪中.
